Avebury is a less well-known stone circle than Stonehenge, but it covers a far bigger area – it’s huge. The outer circle has a diameter of over 1,000 ft (305 m). Plus, unlike Stonehenge, you can actually walk up and touch the stones, at the moment at least. The bottom photo shows a close up of one of the surviving Avebury stones – the biggest ones weigh over 40 tons (36 tonnes) and are 14 ft (4.2 m) in height.
